The closed bottom prevents solder from wicking into the socket during wave or hand soldering, which keeps the contact beam clean and the pin insertion force consistent. With a socket depth of 0.275\" and overall length of 0.288\", the pin seats fully without bottoming out on the board surface. ## Comparing gold vs tin finish options Gold gives lower and more stable contact resistance over many cycles — important if the socket sees frequent pin insertions in a field-service or test application. Tin is cheaper but wears faster and can oxidize in high-humidity environments. For a one-time solder-in application, tin is adequate; for repeated mating, the gold version is the right call. The closed-bottom feature on 5050871-5 and 5050871-8 keeps solder out; the open-bottom siblings (5050871-1 and 5050871-6) allow flux residue or solder to enter the socket cavity, which can interfere with pin insertion in dense boards.","metaTitle":"5050871-5 TE Connectivity PCB Pin Socket, Closed Bottom","metaDescription":"5050871-5 TE Connectivity AMP PCB pin socket, closed bottom, accepts 0.042\"-0.049\" pins, gold 30µin, beryllium copper.
